我正在构建一个使用 *.txt 文件形成资产的 android 应用程序。但我的 *.txt 文件有一些 unicode 文本，我的手机无法显示它们。我能做些什么？这是我的 PlistHelper 类：
public class PListHelper {
public static String readQuizzesListFromAssets(Context context) {
StringBuffer sb = new StringBuffer();
BufferedReader br=null;
try {
br = new BufferedReader(new InputStreamReader(context.getAssets().open("quizzesList.plist")));
String temp;
while ((temp = br.readLine()) != null)
sb.append(temp);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
br.close(); // stop reading
} catch (IOException ex) {
ex.printStackTrace();
}
}
Log.i("PListHelper", "input: "+sb.toString());
return sb.toString();
}
public static String readConfigFromAssets(Context context) {
StringBuffer sb = new StringBuffer();
BufferedReader br=null;
try {
br = new BufferedReader(new InputStreamReader(context.getAssets().open("config.plist")));
String temp;
while ((temp = br.readLine()) != null)
sb.append(temp);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
br.close(); // stop reading
} catch (IOException ex) {
ex.printStackTrace();
}
}
Log.i("PListHelper", "input: "+sb.toString());
return sb.toString();
}
